DIN 5480-2:2006-05

Validity This standard is valid from 2006-05-01.

Foreword

Involute splines in accordance with ISO 4156 are based on module series. These are not interchangeable with involute splines conforming to the DIN 5480 series of standards. The DIN 5480 series of standards is based on reference diameters that are independent of the module, allowing an optimal fit to standard ball and roller bearing diameters and reducing the number of different tools required for manufacturing. This series of standards has been revised by Technical Committee 2.1 Passverzahnungen (“Involute splines”) of the Normenauschuss Maschinenbau (Mechanical Engineering Standards Committee). The revision was considered necessary since a review of the DIN 5480 series of standards in accordance with DIN 820-4 had shown that the series had structural and editorial weaknesses. The object of the revision was to combine the individual parts of this standard in a practical, sensible manner. The entire series of standards now consists of only four parts instead of the previous sixteen. DIN 5480 Involute splines based on reference diameters now comprises: ⎯ Part 1: General ⎯ Part 2: Nominal and inspection dimensions ⎯ Part 15: Inspection ⎯ Part 16: Tools The new edition of DIN 5480-1 deals with fundamental principles, the same as its predecessor, but now also includes fit dimensions and tolerances, these being formerly contained in DIN 5480-14:1986-03. The calculation formulae, tolerances and deviations contained in Part 1 also apply to the other parts of this series of standards. DIN 5480-2 now contains the nominal dimensions and inspection dimensions for the range of items stated above, and incorporates the contents of the former editions of DIN 5480-2 to DIN 5480-13. DIN 5480-15 covers quality inspections of spline joints. DIN 5480-16 defines the design features of tools for manufacturing involute splines.

This series of standards deals with involute splines and spline joints within a module range of 0,5 to 10, having a number of teeth ranging from 6 to 82 and with a pressure angle of 30°. The DIN 5480 series of standards is limited to splines with a pressure angle of 30°, since pressure angles of 37,5° and 45° are covered by ISO 4156.

DIN 5480-2:2006-05

Amendments

a)

The title has been changed to “Involute splines based on reference diameters”.

b)

The full root radius has been included for shafts.

c)

Cold-rolling has been included as a manufacturing process for shafts.

d)

The measuring circle (ball or pin) diameters have been taken from DIN 3977, with one exception.

e)

The standard has been editorially revised.

This standard differs from DIN 5480-2:1991-10, DIN 5480-3:1991-10, DIN 5480-4:1991-10, DIN 5480-5:1991-10, DIN 5480-6:1991-10, DIN 5480-7:1991-10, DIN 5480-8:1991-10, DIN 5480-9:1991-10, DIN 5480-10:1991-10, DIN 5480-11:1991-10, DIN 5480-12:1991-10, DIN 5480-13:1991-10 and DIN 5480 Corrigendum 1:1995-11 as follows:

DIN 5480-2:2006-05

Scope

a)

They have a standard pressure angle of 30°.

b)

The basic rack profile is the same for all pitches, therefore applying a uniform design rule to all profiles.

c)

They have a side fit profile (a diameter fit is permitted in some cases).

d)

Addendum modification is used in order to achieve specific reference diameters.

e)

The fit system includes tolerances for effective form deviations so that the effect of such deviations on backlash is taken into account. The specified range of fundamental deviations and tolerance classes takes due consideration of all requirements.

Involute spine joints as in this standard are used for connecting hubs and shafts either with a removable connection, a sliding fit or a permanent fit. They have all the characteristics required for centring the parts and transmitting torques, as well as meeting all the requirements for economical manufacturing. The theoretical root diameters for hubs and shafts where the dedendum of the basic rack profile, hfP, is 0,55 ⋅ m. The dedendum depends on the manufacturing method used, and can therefore have various values (see DIN 5480-1, Table 3). The root diameters depend on the dedendum.

Basic data

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

Nominal dimension

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.

These tooth thickness measurements are not reliable because they were made near the root fillet or the edge of the tip. Measurements between and over measuring circles are preferable. Deviations and tolerances can result in the unreliability of other tooth thickness measurements not identified by a.
